Piston rings seal the gap between the piston and cylinder wall, controlling oil consumption and maintaining compression. Worn rings cause excessive oil burning, blue exhaust smoke, loss of power, and increased blowby gases. Ring replacement is a significant engine repair but can restore compression and oil control without a full rebuild.
Piston ring wear is gradual and often accompanies high mileage. The symptoms become progressively worse as the seal between piston and cylinder deteriorates.
Ring replacement requires engine disassembly. The cylinder bore condition determines whether rings alone will suffice or whether re-boring is needed.
